Coaxial Loudspeaker
A coaxial loudspeaker is a loudspeaker system in which the individual driver units radiate sound from the same point or axis. Two general types exist: one is a compact design using two or three speaker drivers, usually in car audio, and the other is a two-way high-power design for professional audio, also known as single-source or dual-concentric loudspeakers. The design is favored for its compactness and behavior as an audio point source. Professional audio Coaxial loudspeakers in professional audio enable sound from two drivers to come from one source. This characteristic allows a wider field of listening to a synchronized summation of speaker drivers than loudspeaker enclosures containing physically separated drivers. As well, the pattern of response is symmetric around the axis of the loudspeaker. Since the 1943 introduction of the Altec Lansing Duplex 601 coaxial driver, recording studio monitors have often been coaxial loudspeaker designs. In 1945 the improved Altec 604 ...

Matrix Mixer
A matrix mixer is an audio electronics device that routes multiple input audio signals to multiple outputs. It usually employs level controls such as potentiometers to determine how much of each input is going to each output, and it can incorporate simple on/off assignment buttons. The number of individual controls is at least the number of inputs multiplied by the number of outputs. Matrix mixers may be incorporated into larger devices such as mixing consoles or they may be a standalone product. They always have routing and level controls and may also include other features. Matrix mixers are often used in a complex listening space to send audio signals to different loudspeaker zones. They may be used to provide the producer or director different blends of a mixing project for television, film or recording studio. Basics In professional audio, a matrix mixer is used to route audio signals from multiple sources to different destinations. It may be a standalone device or em ...

Stage Monitor System
A stage monitor system is a set of performer-facing loudspeakers called monitor speakers, stage monitors, floor monitors, wedges, or foldbacks on stage during live music performances in which a sound reinforcement system is used to amplify a performance for the audience. The monitor system allows musicians to hear themselves and fellow band members clearly. The sound at popular music and rock music concerts is amplified with power amplifiers through a sound reinforcement system. With the exception of the smallest venues, such as coffeehouses, most mid- to large-sized venues use two sound systems. The main or front-of-house (FOH) system amplifies the onstage sounds for the main audience. The monitor system is driven by a mix separate from the front-of-house system. This mix typically highlights the vocals and acoustic instruments so they can be heard over the electronic instruments and drums. Monitor systems have a range of sizes and complexity. A small pub or nightclub may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field-effect Transistor
The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor. FETs (JFETs or MOSFETs) are devices with three terminals: ''source'', ''gate'', and ''drain''. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. FETs are also known as unipolar transistors since they involve single-carrier-type operation. That is, FETs use either electrons (n-channel) or holes (p-channel) as charge carriers in their operation, but not both. Many different types of field effect transistors exist. Field effect transistors generally display very high input impedance at low frequencies. The most widely used field-effect transistor is the MOSFET (metal-oxide-semiconductor field-effect transistor). History The concept of a field-effect transistor (FET) was first patented by Austro-Hungarian physicist Julius Edgar Lilienfeld in 192 ...

Jesus Christ Superstar
''Jesus Christ Superstar'' is a sung-through rock opera with music by Andrew Lloyd Webber and lyrics by Tim Rice. Loosely based on the Gospels' accounts of the Passion, the work interprets the psychology of Jesus and other characters, with much of the plot centered on Judas, who is dissatisfied with the direction in which Jesus is steering his disciples. Contemporary attitudes, sensibilities and slang pervade the rock opera's lyrics, and ironic allusions to modern life are scattered throughout the depiction of political events. Stage and film productions accordingly contain many intentional anachronisms. Initially unable to get backing for a stage production, the composers released it as a concept album, the success of which led to the show's Broadway on-stage debut in 1971. By 1980, the musical had grossed more than worldwide. Running for over eight years in London between 1972 and 1980, it held the record for longest-running West End musical before it was overtaken by '' ...
